FORT WORTH (CBSDFW.COM/AP) — The brother of a Fort Worth man accused of killing an inmate in a jail cell says his brother shouldn’t have been housed with another person because he’s diagnosed with schizophrenia and has hallucinations.

The Fort Worth Star-Telegram reports that Brandon Flores doesn’t believe that his 43-year-old brother David Flores fatally attacked 76-year-old Clinton Don Simpson because Simpson is an alleged child molester or because of his age.
